Momentum & Energy Extra Study Questions Short Answer 1. What is the momentum of a 1000 kg car moving at 15 m/s [E]? 2. Calculate the momentum of each of the following objects. (a) a 0.50 kg ball thrown upward with a velocity of 30 m/s (b) a 2000 kg railway car moving south at 10 m/s (c) an electron of mass 9.1 × 10–31 kg‚ moving at a velocity of 1.0 × 107 m/s (d) the Earth‚ of mass 6.0 × 1024 kg‚ moving along its solar orbit with a velocity of 3.0 × 104 m/s 3. The momentum of a 7.3 kg shot is 22

ecotourism — travel that preserves the environment and promotes the welfare of local people — continues to gain momentum throughout the world. According to the Quebec Declaration on Ecotourism‚ ecotourism “embraces the principles of sustainable tourism… and the following principles which distinguish it from the wider concept of sustainable tourism: [It] contributes actively to the conservation of natural and cultural heritage; includes local and indigenous communities in its planning‚ development‚ and

What Makes A Ride Thrilling? Year 11 Physics ERT Introduction Theme parks have always been a source of thrills and amusement‚ as well as major source of tourist revenue. As celebrated coaster designer John Allen states: “You don’t need a degree in engineering to design roller coasters‚ you need a degree in psychology” (Focus‚ 2009) For decades‚ thrill rides have implemented psychological thrills such as long upward climbs building anticipation‚ surprise twists and turns‚ and hills that

has also been discovered that the emergence of TEK in Western academic discourse and education structures serves to become stable and change in transmission of cultural techniques about language and education and‚ as a consequence‚ observe how momentum for the search regularly grows while conceptions of ecosystems in traditional societies coincide‚ at least to a point‚ with the ones of useful resource managers who favors most modern interpretations of environment concepts.

Hoo Sze Yen Form 4 Experiments Physics SPM 2008 CHAPTER 1: INTRODUCTION TO PHYSICS 1.1 PENDULUM Hypothesis: The longer the length of a simple pendulum‚ the longer the period of oscillation. Aim of the experiment: To investigate how the period of a simple pendulum varies with its length. Variables: Manipulated: The length of the pendulum‚ l Responding: The period of the pendulum‚ T Constant: The mass of the pendulum bob‚ gravitational acceleration Apparatus/Materials: Pendulum bob‚ length

Fs W = Fs When an object is moved away from a gravitational field‚ it gains energy. This is because by raising it up from the field’s origin‚ work is done. E.g. An object 1kg in mass is raised 100m‚ the work done would be 980J. However‚ conservation of energy states that energy cannot be destroyed. Therefore the object now has 980J in gravitational potential energy. Whereas at the origin is would have 0J potential energy. Fg = Gm1m2d2 Fg = Gm1m2d2 Ep = 1.1.3 Perform

Antônia C. Physics HL Aspects of Physics Case Study: Amusement Parks On the 26th of February‚ 2011 our class went on a field trip in order to analyse the aspects of physics present in amusement parks. I chose two aspects based on my favourite rides: ‘Kaboom’ (which works based on free-fall) and the roller coaster. The Physics of Roller Coasters How does a Roller Coaster work? Roller coasters have no engines (although many still tend to think they do) and are thus not propelled around the
